In terms of acid and alkali resistance, the acid and alkali resistance of PVC sheet is better than that of PP sheet, but the texture is more brittle and hard, resistant to ultraviolet radiation, can withstand climate changes for a long time, is not flammable, and has light toxicity. However, the PP sheet is not UV proof, and it will change color if exposed to sunlight for a long time.
PP sheet is a commonly used sheet in our lives, and many times we need to process it in plastic. Which method to choose depends on the technical conditions of the PP sheet parts and different usage requirements.
In actual production, although the shape, size and use occasions of the pipe fittings are different, its processing procedures are the same and are divided into several steps. Each processing procedure can be realized by different processing methods. Compared with sheet plastic processing, although they have many similarities in terms of deformation properties, deformation characteristics, etc., there are many similarities between them, but in terms of process methods, process difficulties to be resolved, and tooling There are big differences in structural design, process parameter selection, and process measures taken to prevent product quality defects, and there are different reasons.
